prim-am ification Germany February, 1957 e or. 242-4181) The presentinvention relates to improvements in yarn supporting reels. 1 Moreparticularly, the present invention relates to a perforatedfrusto-conical -supporting reel for laps of yarn which is to be used forwet and dry treatments of the yarn.

Yarn supporting reels, such as were known prior to the presentinvention, which were radially compressible and essentially consisted ofthe coils of a spring had the disadvantage that the shrinking of thelaps of yarn, and especially of rayon, would tighten the same around thecoils of the spring to such an extent that the individual layers of theyarn would'penetra't'e between the individual coils toward the inside ofthe reel. The dye or other treating fluid could not then penetratethrough the inner parts of the" yarn laps which were engaging with thecoils of the spring to the same extent as the exposed r portions of theyarn.

.- :It is an 'object of the present invention to provide a yarnsupporting reel which overcomes the above-mentioned disadvantages of thereels which were previously known, and which comprises a rigid,perforated, frustoconical yarn supporting reel which has an annular lapsupporting plate at the lower end thereof, and the shape of whichpermits, several of such reels to be superimposed upon each other in atelescopic relation, in accordance with the height of the lap of yarn.

It is another object of the present invention to provide the rigid,perforated yarn supporting reel with deep notches in its upper conicalend portion so as to form intermediate prongs, and to support the reelat the inside thereof by means of a central spacing tube which permitsthe desired number of reels to be superimposed in a telescopic relationupon each other and to he removably mounted on a single spindle in anupright position one above the other. When the individual reels are thussuperimposed upon each other, a plurality of supporting walls, whichextend radially from the central spacing tube, interengage with theupwardly projecting prongs of the reel underneath, while the spacingtubes a-but against. each other and thus limit the extentto which thelaps of yarn on the reels can be compressed. These spacing tubes arepreferably made of a length or height which corresponds to that of thelowest lap, while for higher laps, the individual spacing tubes may belengthened by extension rings or tubes.

It is a further object of the present invention, to provide a yarnsupporting reel of the type as above described in which the outerfrusto-oonical sleevelike part of the reel is exchangeable for one of adifferent outer diameter. For this purpose, the reel is made of two"separate parts, that is, an outer sleevelike part and an innersupporting part which includes the lower annular supporting plate uponwhich the lap'is placed, the central spacing tube mounted thereon, andthe radial supporting walls which, when the two parts of the reel areassembled, connect the frusto-conical 'sleeve part with 2,936,964Patented May 17, ,1 960 2 the spacing tube. The inner wall ofthefrusto-conical sleeve part is further provided with a suitablesupporting membeiy'for example, a substantially U-sha'ped ring which isadapted to engage into suitable recesses in the -upper ends of theradial supporting walls so as to center the outer sleeve part relativeto the spacing tube, It is thus possible to use the same supportingplateand spacing tube for. various frusto-conical sleeve .parts ofvdiftferent diameters. v I s It is yet another object-of thepresentlinvention to provide a yarn supporting'reel which consistsin theprovision of projecting portions or hooks on the last-mentionedsupporting ring on the inner wall of the frustoconical sleeve part ofthe reel, and suitable apertures in the radial supporting walls. A smallturn of the outer sleeve relative to the inner supporting part will movethe books into engagement with the apertures and thereby lock the twoparts of the reel to each other in the axial direction thereof.

With these and other objects inview, which will become apparent in thefollowing detailed description, the present invention will beclearly-understood in connection with the accompanying drawings, inwhich:

Fig. 1 is a perspective from view of a yarn supporting reel, accordingto the present invention, with an annular .lap supporting plate;

Fig. 2 is an axial cross sectionthereof;

Fig. 3 is a top plan view'thereof;

Fig.4 is an axial cross section of a plurality of superimposed yarnsupporting reels, according to the present invention, with yarn lapsthereon and mounted on a receiving spindle; p V .Fig. 5 is a cross:section along the lines 5-5 in Fig. 4;

Fig. 6 is an axial cross section of a two-part yarn supporting reel,disclosing a modification of the present invention; and

Fig. 7 is the yarn supporting reel, shown in Fig. 6, in the assembledposition.

Referring now to the drawings, the yarn supporting reel 1, according tothe present invention, is of frusto-conical shape, and its upper end isprovided with long prongs 2 which are adapted to engage into the lowerend of a superimposed reel of the same type and design. Reel 1 is made'of a rigid construction and provided with a large number of aperturesso as to permit the treating fluid topass from the inside of the reelthrough a lap of yarn thereon. A tubular member 3 at the center of thereel 1 supports the latter by means of a plurality of radial wallportions 4 and is connected by radial arms 6 to an annular lapsupporting plate 5 which, in turn, supports the lower end of reel 1.

If several reels 1 with laps of yarn thereon are superimposed upon eachother, as illustrated in Figs. 4 and 5, the central tubular members 3 ofthe individual reels 1, serving as supporting and spacing elements, maybe mounted above each other. on a spindle'7, while the prongs 2 at theupper end of each reel 1 engage into the lower end of the respectivesuperimposed reel 1 and surround the radial wall portions 4 thereof. Thelaps of yarn on the individual reels 1 can therefore be com 1' and asupportingpart which consists of the annular lap supporting plate 5',the supporting the spacing tubewith respect to the spacing tube 3', theinner wall of the reel carries a ring 9 of substantially U-shaped crosssection, the inner wall of which is adapted to engage into notches 10'in the upper end portion of the radial walls 4. In order to retain thesleeve 1 also in the axial direction onth'e spacing tube 3' with theplate 5' thereon, the ring 9' has one or more safety hooks 11' which,after the ring 9 has been placed upon the radial walls 4, may be engagedinto recesses 12' in the walls 4' by a small turn of the sleeve 1' so asto lock the two parts together. The reels, when thus assembled, may thenbe superimposed upon each other in the same manner as described withrespect to Figs. 2 to 4.

Although my invention has been illustrated and de scribed with referenceto the preferred embodiments thereof, I wish to have it understood thatit is in no way limited to the details of such embodiments, but iscapable of numerous modifications within the scope of the appendedclaims.

I claim: 7
